Answer:
- Variable x in first equation
Step-by-step explanation:
<u>Given system</u>
Variables in this system are x and y.
Isolating a variable means rearranging the equation so that a variable of our interest is on its own in one side of the equal sign.
We see <u>variable x is isolated </u>in the first equation.
In the second equation both of the variables are on the same side so they are not isolated.
